feat: manual payment package-based + StockMovement constraint fix

- ManualPayment: add package_id to proto, handler selects package by ID
- ManualPayment: remove manual amount input, use package price
- ManualPayment: validator now checks PackageId instead of Amount
- StockMovement: fix CHECK constraint (store negative qty for decreases)
- StockMovement: Reserved/Released don't change physical Quantity
- Proto NuGet bumped to 0.0.192
